Quick answer: Sinningia seeds are dust-tiny and need light. Surface-sow them on moist, fine mix, keep them under a dome at 70–75°F, and expect sprouts in 2–4 weeks.

gloxinia seeds

instructions

  1. Moisten the soil very well- use either coconut fiber or a fine succulent potting mix(nothing too chunky!).
  2. Surface sow. Tap seeds on the surface of the soil; don't cover.
  3. Dome on at all times, keep consistently at 70–90°F in bright indirect light or under a grow light.
  4. Bottom-water so seeds don't wash away.
  5. Repot once seedlings have 2–3 leaves.

things to know

  • This is Sinningia speciosa, the florist's gloxinia, not the trailing Gloxinia genus.
  • Grows a tuber: it rests after flowering and regrows from the tuber.
  • Grown like African violets: they're cousins. See our African violet guide.
  • Pick a planter that holds moisture: plastic, rice hull or ceramic, with a dome. Skip terra cotta, peat pots, coco coir pots and egg cartons. They wick water away from the seed.

plant care tips

  • Light: bright indirect light or a grow light.
  • Water: bottom-water with room-temperature water; keep leaves dry.
  • Rest: when it stops blooming and fades, cut back watering and let the tuber rest 1–3 months.
  • Feeding: bloom fertilizer every 2–4 weeks while growing.

faqs

Is gloxinia the same as Sinningia?

The florist's gloxinia is Sinningia speciosa. That's what these seeds are.

Why is my gloxinia dying back?

It's probably going dormant. Rest the tuber and it will regrow.

Is gloxinia pet-safe?

Sinningia is listed as non-toxic to cats and dogs.

these are key aspects of your setup

check your setup!

  • 💡light: is your setup away from direct sun? these seeds should stay in indirect or filtered light, or better yet, under grow lights.
  • 💧moisture: does the soil feel very moist to the touch?
  • 🌡️temperature: is the setup away from direct sun, open windows, or heat vents? make sure it stays consistently between 70F-90F (use a heat mat if the temperature falls under 70F)
  • ☁️humidity: do you see condensation on the humidity dome? if not, make sure the dome is fully sealed, the setup is warm enough, and there's enough moisture in the soil.
  • 💚care: leave the dome on and only open it once a week to add water.
